A method and system for monitoring a packet network by using call detail records (CDRs) are disclosed. The method first receives at least one call detail record (CDR) at a completion of a call from at least one voice gateway router that serviced said call and analyzes said at least one CDR. The method then monitors at least one performance parameter in accordance with said at least one CDR.

Method and apparatus for detecting a network impairment using call detail records

A method and system for enabling a network service provider to monitor a packet network by using call detail records (CDRs) are disclosed. The method first detects a termination of a call by at least one voice gateway router and generates a call detail record (CDR) at said termination of said call by said at least one voice gateway router. The method then forwards said call detail record by said at least one voice gateway router to at least one CDR collecting and analysis server.

Method and apparatus for monitoring a packet network

A method and apparatus for managing a virtual private network are disclosed. For example, the method collects performance data for at least one parameter from a plurality of customer edge routers and a plurality of provider edge routers associated with the virtual private network. The method correlates the performance data for identifying one or more performance exceptions based on a threshold for each of the at least one parameter, and performs a trending analysis using the one or more performance exceptions to predict a potential problem that will impact the virtual private network.
